I think about it as well quite often. I have fond memories of slope and smash especially and sometimes I wish and dream to run up slope combine once more. I would even pay just to have a slope game. If you guys had split off and did something like GM Tower > Tower Unite, I would support you in a heartbeat.
Sometimes it's truly wild to think back and realize it has been about 8 years since my first time on Moronyard, and about 2 or 3 since my last. If you were to at least give the game mode so I could play it offline by myself I would be ecstatic, but I'm not sure if it would be fair to ask of that. I would gladly pay.
I hope you're all doing well. Wishing you all health and happiness!
